Piastra in alluminio aeronautico, as aluminum plates designed and used specifically for the aviation field, have become an indispensable and important material for modern aviation manufacturing due to their high strength, light weight and good corrosion resistance.

Entrambi 7075 e 7475 aviation aluminum plates belong to the 7 lega di alluminio di serie. They are super-hard aluminum alloys in the aviation aluminum series and have good wear resistance, corrosion resistance and mechanical properties.

Entrambi 7075 e 7475 aviation aluminum plates contain zinc (Zn) and magnesium (mg) as the main alloy elements. The MgZn2 structure formed by these elements has a significant strengthening effect, making both alloys characterized by high strength and high hardness.

7075 aluminum alloy may be slightly inferior to 7475 aluminum alloy in strength, ma 7475 aluminum alloy has better fracture toughness while maintaining high strength. This makes 7475 aluminum alloy more advantageous in certain application scenarios where both strength and toughness need to be considered.

The corrosion resistance of 7075 aluminum alloy is relatively poor, while the 7475 aluminum alloy has better corrosion resistance. This may be due to the addition of more alloying elements to the 7475 Lega di alluminio, forming a denser oxide film, thereby improving its corrosion resistance.

7075 piastra in alluminio aeronautico:

Forza: tensile strength σb (MPa) ≥ 560, yield strength σp0.2 (MPa) ≥ 495.
Plasticity: The plasticity is good after solution treatment, and the strengthening effect of heat treatment is good.

7475 piastra in alluminio aeronautico:

Forza e tenacità: High strength and good fracture toughness.
Resistenza alla corrosione: Has better corrosion resistance.
Other properties: Specific mechanical properties such as tensile strength, yield strength, eccetera. may vary depending on the specific state and processing method.

7075 piastra in alluminio aeronautico: mainly used to manufacture aircraft structures and other high-stress structural parts that require high strength and corrosion resistance, such as aircraft upper and lower wing wall panels, traverse, eccetera. Inoltre, it is also widely used in mold processing, mechanical equipment, tooling fixtures and other fields.

7475 piastra in alluminio aeronautico: mainly used for aluminum-clad and non-aluminum-clad plates for fuselage, wing frames, traverse, eccetera. and other parts that require both high strength and high fracture toughness.

Aircraft aluminum sheets are specially treated to provide extremely high strength and rigidity while maintaining a low density. This property makes it ideal for manufacturing lightweight, high-strength aerospace components, helping to improve the overall performance and fuel efficiency of aircraft.
